摘要
当前川南页岩气开发面临各类环境敏感区、岩溶发育区等影响选址选线,基本农田保护、土地管理政策等致使征地形势越发严峻,区域固体废物处置能力与不断增长的钻井岩屑需处理量间的矛盾日益突出,钻井岩屑处置压力愈来愈大,压裂返排液处理难度大,达标外排存在经济技术可行、排放标准等瓶颈,深层回注措施存在非技术风险。针对川南页岩气开发面临的环保形势,分别从开发布局、用地保障、钻井岩屑和压裂返排液处置4个方面提出相应的对策建议。
Currently,shale gas site selection and determination in Southern Sichuan was affected by environmental sensitive and karst developing areas.In the meantime,basic farmland protection and land management policy have also made it hard for land expropriation.The contradiction between the current regional solid waste disposal capacity and the increasing amount for drilling cuttings has become increasingly prominent,following the pressure on drilling cuttings disposal is increasing.Furthermore,the difficulty in the processing of flowback fluids,the standard discharge is still facing the bottleneck of economic feasibility and emission standards et al,and non-technical risks exist with deep reinjection measures.In response to the above environmental protection constraints,the corresponding countermeasures were putting forward,respectively,according to the development distribution,land use safeguard,drilling cuttings and fracturing flowback fluids.
